摘要：
The invention relates to the field of surgery, and more specifically to medical surgical instruments used in neurosurgery. The object of the utility model is to provide a device for the resection of cartilage and bone and subsequent treatment with adjacent vertebral bodies, providing reduction in trauma and laboriousness neurosurgical operations, simplifying forming bed for interbody fusion as well as more manufacturable and less time-consuming at manufacturing in series production. The apparatus comprises a loop cutting portion, the rod and the handle, the loop is provided with transverse cutting elements. One of the cutting elements is provided with a radiused front and rear straight cutting edges. Most of the holes in the loop formed by conjugation central radius and side flat walls. Side flat wall provided with a notch. Step notches calculated according to the formula tn = 1 / 2tre where tn - Step incision tre - a step of cutting elements. Using the apparatus allows qualitatively resect cartilage and bone tissues and the subsequent processing of adjacent vertebral bodies. Execution unit with the proposed features can reduce surgery time, reduce labor intensity, and traumatic brain surgery, to simplify the formation of the bone bed to receive interbody fusion and bone bed with the required parameters. The apparatus is more manufacturable and less labor-intensive in the production in batch production compared with the prototype. The proposed device is suitable for use in neurosurgery, neurotraumatology, orthopedics and neyroortopedii.Полезная модель относится к области хирургии, а конкретнее к медицинским хирургическим инструментам, используемым в нейрохирургии. Задачей полезной модели является создание устройства для резекции хрящевой и костной ткани и последующей обработки смежных тел позвонков, обеспечивающего снижение травматичности и трудоемкости нейрохирургических операций, упрощение формирования ложа для межтелового спондилодеза, а также более технологичног
